Masterpiece has made a huge cast change to its popular drama, Miss Scarlet and the Duke, which will be returning for a fifth season.

On his exit from the show, Stuart, who has starred in the previous four seasons, said: "It has been such an incredible joy to bring Duke to life through Rachael's beautiful, brilliant writing, and to get to play him for the past four years. 

"But it felt like the time was right for Scarlet to explore new stories and challenges for now, as the show continues to grow and evolve. I will miss working with my amazing partner in crime Kate and the rest of our brilliant family and team, but I'm excited to continue following Eliza and her escapades as a huge fan and newly enrolled Scarleteer!"

Kate added: "I will miss working with my pal Stu every day, and know Eliza will miss her Duke, but I think the best is yet to come for her. I can't wait for fans to see what we have in store for Season 5."

While Stuart won't be returning to the show, other familiar faces will be reprising their roles, including Evan McCabe as Detective Fitzroy, Cathy Belton as Ivy, Felix Scott as Patrick Nash, Paul Bazely as Clarence, Simon Ludders as Mr. Potts, and Tim Chipping as Detective Phelps. 

Taking to social media, fans couldn't help but express their disappointment at the news. One person penned: "This is a huge mistake! Eliza & William's chemistry was what made the show special."

Other fans were excited by the renewal news, however, with one person writing: "Thank you for being upfront and honest—that's commendable and respectful to your fanbase when TOO MANY networks are not. I am here for Scarlet and can't wait for Season 5!"

Commenting on Stuart's departure, series creator Rachael New said: "We will miss our Duke but there is so much in store for Eliza – new crimes, new friends, new foes and new romance. We will be keeping her very busy!"

Meanwhile, Masterpiece Executive Producer Susanne Simpson added: "This new chapter in Eliza's story is going to bring our audience more of what they've come to love about this series – mystery, humor, potential romance and most of all, Kate Phillips' terrific performance as Miss Scarlet."

Fans will be pleased to know that filming for season five is underway in Belgrade, Serbia, with additional casting to be announced in due course. 

For those unfamiliar with the mystery series, it's set in 1882 Victorian London and follows Eliza Scarlet, the whip-smart and fearless daughter of renowned private detective Henry Scarlet. When her father suddenly dies, Eliza uncovers his considerable debts. With her only option to take over the family business, Eliza must navigate a man's world and face all manner of obstacles, including Victorian conventions conspiring to keep a woman from working as a detective.
